SCAFFOLDlNG-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 728,595, dated May 19,1903.

Original application filed November 14, 1902, Serial No. 131,315.Divided and this application filed January 24, 1903. Serial ITO-140,376.(No model.) I

To aZZ whom it may concern: Be it known that I, ALEXANDER MENOZAR- SKI,a citizen of the United States, and a resi- I and support therefor,applicable in many. branches of the building art, as will be apparent topersons skilled therein, and especially useful in connection with thebuilding construction disclosed in my copending application for LettersPatent, filed November 14, 1992, Serial No. 131,315, of which thepresent application is a division.

In carrying out the invention I provide a number of hangers having threesides or limbs and formed of metal flattened in the plane of the hanger,the upper ends of the hanger being turned over to form hooks capable ofremovable engagement with the bottom flanges of I-beams or likestructures. These hangers are arranged facing each other in pairs andserve to support cross-beams which are wedged securely in between theI-beams and the bottoms of the hangers. On these crossbeams are placedplanks forming the scaffoldfloor, and when the invention is used inconnectionwith the building construction forrn iug the subject-matter ofmy copending application referred to cement or other plastic material isplaced on this floor and allowed to set, after which the cross-beams,planks,-

and hangers are removed. I also employ a number of caps which arearranged to set over the hooks at the upper ends of the hangers, so asto prevent the cement from setting in the hooks and interfering with theeasy removal of the hangers. After the hangers and caps are removed theopenings formed in the cement by the caps may be filled up by the useofa trowel or in any other convenient manner.

This specificationis an exact description of one example of myinvention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar characters of reference indicate corresponding parts inboth the views.

Figure l is a sectional view taken across the l-beam and showing thehangers with the beams and planks in operative position, this view beingsectioned on the line 1 1 of Fig. 2; and Fig. 2 is a sectional view onthe line 2 2 of Fig. l.

(1 indicates the I-beams, two of which are illustrated in Fig. l. I

The hangers comprise each a bottom limb b with side limbs I). Thesehangers are formed of metal flattened in the plane of the v hangers, sothat the strain is borne edgewise on the metal, and great strength isthereby attained. The upper ends of the limbs of the hangers are turnedover sidewise to form hooks b These hooks, as best shown in Fig. l, arethe means by which the hanger is supported. According to the examplegiven in the drawings the hooks are engaged by the bottom flanges of theI-beams, so that the hangers depend therefrom. This constructionprovides a most secure hanger which is capable of sustaining greatweight.

The hangers are arranged in pairs, the members of which face each otherin lines transverse to the I-beams, and each pair of hangers supports across-beam 0. These beams are fastened firmly in place by means ofwedges d, which are here shown to be arranged between the bottoms of theI-beams and the top face of the cross beams and which coact with blockse, arranged under the bottom of the cross-beam. These blocks are,however, not absolutely necessary, or they may, if desired, be replacedby wedges similar to the wedges d. It is only essential that thecross-beams be fastened securely in place, so as to make the parts a, b,and c rigid with respect to each other.

When the parts a, b, and c are in the, position shown, the temporaryplank flooring or scaffolding f is placed over the cross-beams c,notches f being cut in the planks f, so that the hangers may passthrough them. The scaffolding and its appurtenances thus arranged maybeus'ed in'numerous Ways. If it is to be used for forming the buildingconstruction shown in my before-referred-to copending application, thecement or other plastic material should be molded directly on the planksf. In this case caps g are employed to cover the hooks 19 These caps areopen at their bottoms and are rested on the floor f in the positionshown in the drawings. This prevents the cement from setting in thehooks and allows the easy removal of the hangers after the arches haveset or become hard.

Various changes in the form, proportions, and minor details ofmyinvention may be resorted to at will without departing from the spiritand scope thereof. Hence I consider myself entitled to all suchvariations as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A hanger for the purpose specified,said hangerhaving a lower portion to engage a joist or beam, and side limbsprojected upward from the lower portion, the hanger being formed ofmetal flattened in the plane of the hanger, and the upper ends of saidside limbs being bent sidewise and downward to form hooks for supportingthe hanger.

2. A hanger for the purpose specified, said hanger being formed of metalflattened in the plane of the hanger and having a lower portion toengage a joist or beam and an upper portion to engage a supportingmember such as an I-beam, said upper and lower portions of the hangerbearing edgewise on the joist and support.

3. The combination with two supportingbeams, of hangers engagedtherewith, beams or joists extending transversely of thesupporting-beams, and held in the hangers, a scafiold-flooring placed onthe second-named beams, and wedges entered between the two beams, forthe purpose specified.

4. In a scaffolding, the combination with the supporting members, ofhangers connected therewith, beams or joists sustained in the hangers,Wedges entered between the beams or joists and the supporting member,and a scaffold-flooring placed on the beams.

5. In a scaifolding, the combination with the supporting members, ofhangers connected therewith, beams or joists sustained in the hangers,wedges entered between the beams or joists and the supporting member,and a scaffolding-flooring placed on the beams, the said hangers beingformed of metal flattened in the plane of the hangers and having theirupper ends bent over sidewise and downward to form hooks.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALEXANDER MENOZARSKI.
